Title:
ROBOT, POWER TRANSMISSION DEVICE, AND POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/055683
Kind Code:
A1
Abstract:
The present invention comprises: a ball screw having a screw shaft; a coupling device having provided therein a first fitting hole and a second fitting hole and being fastened to the screw shaft fitted into the first fitting hole; a motor that rotates an output shaft; and a power transmission device having a first rotating section having a third fitting hole opened therein into which the output shaft can be fitted, a second rotating section having protruding therefrom a protruding shaft that can be fitted into the second fitting hole, and a transmission section that transmits the rotation of the first rotating section to the second rotating section. In a state in which the output shaft and the screw shaft are arranged upon different axes, the coupling device is fixed to the second rotating section as a result of: the output shaft, fitted into the third fitting hole facing one side in the thrust direction, being fixed to the first rotating section by being coupled to the first rotating section; and the protruding shaft being fitted into the second fitting hole and coupled to the coupling device. On the other hand, the coupling device is fixed to the output shaft as a result of the output shaft being fitted into the second fitting hole and coupled to the coupling device, in a state in which the power transmission device is detached from the output shaft and the coupling device and the output shaft and the screw shaft are arranged upon the same axis.
